## step_mode property


Gets or sets the key's step mode.
If the interpolation type is [`Interpolation.CONSTANT`](/3d/python-net/aspose.threed.animation/interpolation#CONSTANT), list.data[index] decides which key-frame's value will be used during interpolation.  
A [`StepMode.PREVIOUS_VALUE`](/3d/python-net/aspose.threed.animation/stepmode#PREVIOUS_VALUE) means the left key-frame's value will be used  
A [`StepMode.NEXT_VALUE`](/3d/python-net/aspose.threed.animation/stepmode#NEXT_VALUE) means the next right key-frame's value will be used
